benelli replied to Abonino's topic in 2014 - 2018 Chevy Silverado & GMC SierraDoes anyone know if there doing this TSB 18-NA-355 here in Canada. My dealer called me yesterday after i complained to the owner about them booking me in and not doing the fluid exchange with the new Mobile 1 HP fluid. Service managed emailed me back and said they would do that TSB for me to give them another chance to make good. they also said they would give me a loaner truck while it was being done. Iam sceptical whether they even have this fluid yet here in canada. or are they just tring to get me in the service bay again. Can anyone confirm if GM has this fluid in stock here in Canada? Part number is 1935349 i beleive.
benelli replied to Abonino's topic in 2014 - 2018 Chevy Silverado & GMC Sierrawasting your time . I was just there today to do the trans flush with the Mobile 1 HP fluid. I was re assured by the service manager that he would do the so called fix. So I drop the truck off last nite. I called around 2 pm in the afternoon he tells me there was no shutter so the 18-NA-355 TSB cant be done. WTF I said my truck sat there all day after you tell me there doing this fix> Now you tell me its not being done. There reply was the transmission is normal operation. So they drove my truck 25 klm all day probably when for luch with it. kept it there all day only to tell me there are no updates which I already knew and no trans flush so basically a waste of time. there plain liers at the dealerships especially at the service departments. its all about how many customers they can reel in and rip off or charge GM under warrenty.
1000 miles ? No kidding mine was good for about that too. Then one day rolling out slow from a gas station BANG like someone rear ended me. First thing my dealer service guy said it’s an adaptive transmission . Try not to let off the gas when you roll away . He told me to adjust my driving habits . Lol . I don’t even know how any idiot in his right mind could even say that . They must be brainwashed to believe this crap even themselves. 58 Grand to adjust my driving habits to a vehicle. All I can say is that this day and age with all the forums and internet searches the days of fooling customers is over. They should wake up . Cus there truck line is we’re the money is at for them . There car lines are ugly other than corvette and Camaro .
benelli replied to RyanbabZ71's topic in 2014 - 2018 Chevy Silverado & GMC Sierracheck out all the issues with the transmissions you may change your mind.
Honestly your better off just trading in for another truck manufacturer. Your going to waste your time and get so frustrated. gm will never admit to a shotty design build on these transmissions. they should be ashamed of themselves. Thats why they offer 0/84 financing the banks get a a cut of the sales of the trucks. thats how they offer that financing. If you look at my earlier posts. not much can be done with the trans. they brush you off as normal operation. I will never buy a GM product again. I know every manufacturer has problems ,but you can usually get them remedied. I had a Ram with an 8 speed. could`t even here it shift through all the gears. spread the word about these crappy truck designs to everyone you now. Maybe Gm will wake up and do the right thing.
They couldn`t even get the 8 speed Transmission right and still tell customers it because its an adaptive transmission. I can make the truck shift with a bang every time now. there is no fix. all the fluid flushes with Mobile 1 synthetic converter replacements Updates relearns wont do a thing. Its a bad design. Ive spoken to many Techs in the industry that are employees and all same the same thing. There horrible they get dozens in a week with same complaints. there told to go thought the same steps - flushes relearns torque converter change - outs. all temp fixes some had transmissions replaced only for them to do the same thing. Bad design is a Bad design. You can Change all the parts you want. still going to run the same. even they dont want to admit it. all they can say is hope your dealership has taken care of your issue. LOL what a joke.
Like the truck just don’t like all the issues and potential issues that will develop down the line. I can understand some minor issues when it’s a new build but the truck don’t run right by the time you get it home from the dealer. I have always been a GM guy but how can I stay loyal with all the problems they have . If they would at least fix the issues properly instead of just brushing it off as it’s normal operation. The lies about “we don’t see many with transmission issues” really it’s all over the internet everybody with same issues. There response is don’t believe what you read on the net. So everybody all over the country just wake up and post these same problems with transmissions with same symptoms Out of the blue . I had a ram 1500 sure it had a few issues but company fixed problems correctly didn’t hide behind there known trans or other problems and fool customers into thinking it’s normal . They just don’t want to make it a recall as it’s not a safety issue so just string along everyone
Nope. as i mentioned in earlier thread the problem is in the software. I spoke with a transmission Tech At my dealership and he told me that they get these transmissions in with same issues every day. They shift that way so you go through all the gears basically from a stop sign to another. They could reprogram it but then is would lower litres per 100klm. Aftermarket tunes from superchips or diablo clean up the shit perameters and the truck runs great. but some fear the program will void warenty if there is an issue. so basically they tell you come in we will do a relearn and drive for a few mor thousand klm. they like to blow smoke up everybodys A**. the service guys are burned out former mechanics that just like to upsale service . they know these transmissions were a flop but they wont admit it. I told a service advisor at the dealership i bought it from about the transmission issues i was having. His response was sorry to here that we normally dont have any problems with these transmissions. REALLY i just spoke with the Trans tech which told me they get dozens aweek in with same issues. i did nt tell the sevice advisor as i did not want to et the Tech in hot water. there all liers.
I hear you Brother. GM is usless.
HERE WE GO!!! My dealership had a solution for my clunky 8 speed transmission. "why not trade it in we have a 10 speed now" LOL LOL LOL . whith all the problems with the 8 speed someone would have to be nuts to pick up a truck with a 10 speed. And look Problems are already begining. Soon there will be a bible of threads about this Transmission.
Lol this is like an episode of the x files. Nobody is saying we need to put on tin foil hats and drive around in our trucks . It’s more of neusance and . Tell me something if you go to the dealer for a rivet do they charge you for that item? Dam straight they will with tax. So no one can still explain it why onstar is actively monitoring your vehicle for no money. It’s not because they like you . Think what you like everyone has there opinions. But I don’t think I should have to call to have my car or truck not monitored. They should be calling me to ask that. Anyway I found a solution to the problem just today. Works great and all my systems work great. Even the transmission clunking has gone shifts great.
Are you aware that they can control all your vehicle functions ! I can easly press the emergency button on my cell phone the same way. Explain to me the logic that onstar has about still being able to track and monitor your vehicle peramerters and functions. If your not paying for for any service . That crap is just another way for your dealership to bend your over for repairs. Gm owns onstar.doenst that make you think
I just want to disable the Onstar don’t need to have them send me reminders of oil changes and things plus I think they probably send down software hits on your truck so you take it in for service.
Anyone know how to disable this crap. they keep sending me emails on maint for the vehicle and odometer reading. I don`t even have a subscription . I believe i saw a white up a while back detailing how to remove the module behind the radio & open it up to remove the communication chip then re-install. Anyone Have a link on the site or were i can find it. Thanks
Report post Posted 2 hours ago Ok here is an update to this harsh shift from rolling stop or 1-2 shifts. I finally spoke with a master Tech at one of my Dealerships. Young service manager very nice guy. Was able to speak with him for a hour. Mechanic To Mechanic. He informed me that they have hundreds of same complaints about the 8 speed transmissions. and that`s only at there dealership. He said its a world wide problem. The transmissions are fine it is definately a software program issue. He advised forget about the relearns and the trans flushing and the all that crap that these dealers do to try and fix the issue. IT WONT WORK. wasting your time and there going to create more problems with tearing it apart trying to change this and that. no Torque converters or anything will fix the issue other than a new software update to address the issue. I asked how about an aftermarket tune from superchips or bear. He said absolutely he would do that on his for this issue. i said well what about the warranty if something goes wrong with the Transmission. Also advised that and if you get my point if there is a major breakdown of the drive train weather it be motor or transmission. Gm Canada will ask for the computer history of ONLY the engine Not The Transmission software. so even if you have a tune in there and dont remove it before you bring it in. He says gm never asks for the transmission software history. On Another note the new 2019s are rolling out soon so they have addressed the issue on these transmissions weather they be 8 speed or 10 speed type. He seems to think they will adapt the new software program to these troublesome transmissions and it will resolve the hard shift issues.
